Introduction:

Lung cancer is one of the leading causes of cancer deaths in women and men in North America. Unfortunately due to the fact that lung tissue contains a lot of blood vessels, any cancer in it will metastasize very early.

This is why at the time of diagnosis of lung cancer 70% of patients have already metastases( 31% regional and 39% distant metastases ) (Ref. 1 and 2).

5 years later only 14% of the patients who initially had regional metastases will still be alive and only 2% of the patients who initially had distant metastases will still live. The reason is that in the initial stages this cancer does not produce any lung cancer symptoms. Because of this lung cancer is diagnosed too late, usually at the point when a chronic cough develops, which does not respond to any medication. Another common presentation is that blood is suddenly coughed up (=hemoptysis) or unexplained weight loss sets in. At this point there is a bronchial cancer present that has invaded locally or has already sent metastases to the brain, the adrenal glands, the liver, bone or skin, in other words the patient is entering into a terminal cancer.
